Why is this medication prescribed?
Buprenorphine and the combination of buprenorphine and naloxone are used to treat opioid dependence (addiction to opioid drugs, including heroin and narcotic painkillers). Buprenorphine is in a class of medications called opioid partial agonist-antagonists and naloxone is in a class of medications called opioid antagonists. Buprenorphine alone and the combination of buprenorphine and naloxone work to prevent withdrawal symptoms when someone stops taking opioid drugs by producing similar effects to these drugs.
How should this medicine be used?
Buprenorphine comes as a sublingual tablet. The combination of buprenorphine and naloxone comes as a sublingual tablet (Zubsolv) and as a sublingual film (Suboxone) to take under the tongue and as a buccal film (Bunavail) to apply between the gum and cheek. After your doctor determines an appropriate dose, these products are usually taken once a day. To help you remember to take or apply buprenorphine or buprenorphine and naloxone, take or apply it around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take or apply buprenorphine or buprenorphine and naloxone exactly as directed. Do not take or apply more or less of it or take or apply it more often than prescribed by your doctor.
You will start your treatment with buprenorphine, which you will take in the doctor's office. Your doctor will start you on a low dose of buprenorphine and will increase your dose for 1 or 2 days before switching you to buprenorphine and naloxone. Your doctor may increase or decrease your buprenorphine and naloxone dose until the medication works properly.
If you are taking the sublingual tablets, place the tablets under your tongue until they completely melt. If you are taking more than two tablets, either place them all under your tongue at the same time or place them under your tongue up to 2 at a time. Do not chew the tablets or swallow them whole. Do not eat, drink, or talk until the tablet dissolves completely.
If you are using the buccal film, use your tongue to wet the inside of your cheek or rinse your mouth with water before you apply the film. Apply the film with a dry finger against the inside of the cheek. Then remove your finger and the film will stick to the inside of your cheek. If you are to use two films, place another film on the inside of your other cheek at the same time. Do not apply films on top of each other and do not apply more than two films to the inside of the mouth at one time. Leave the film(s) in the mouth until they dissolve. Do not cut, tear, chew, swallow, touch or move the film while it dissolves. Do not eat or drink anything until the film dissolves completely.
If you are using the sublingual film, rinse your mouth with water before you place the film. Place the film with a dry finger under your tongue to the right or left of the center and hold the film in place for 5 seconds. If you are using two films, place the other one on the opposite side under the tongue. Do not put the films on top of or near each other. Do not use more than 2 films at one time. Do not cut, tear, chew, swallow, touch or move the film while it dissolves. Do not eat or drink anything until the film dissolves completely.
If you need to switch from one buprenorphine or buprenorphine and naloxone product to another, your doctor may need to adjust your dose. Each time you receive your medication, check to be sure that you have received the buprenorphine product that was prescribed for you. Ask your pharmacist if you have are not sure that you received the right medication.
Do not stop taking or using buprenorphine or buprenorphine and naloxone without talking to your doctor. Stopping buprenorphine or buprenorphine and naloxone too quickly can cause withdrawal symptoms. Your doctor will tell you when and how to stop taking or using buprenorphine or buprenorphine and naloxone. If you suddenly stop taking or using buprenorphine or buprenorphine and naloxone, you may experience withdrawal symptoms such as hot or cold flushes, restlessness, teary eyes, runny nose, sweating, chills, muscle pain, vomiting, or diarrhea.
